There should be a button that pulls up a menu to adjust color/contrast/ bright, etc. Press it and go through the menu options by either repeatedly pressing the menu button, or by using up-down-right left arrows. Adjust your colors using these options, or if available, try "auto" adjust. I don't know this particular monitor, and am no "expert", but these options should be available on virtually any LCD monitor.

This monitor also had a similar problem, it was connected with a dvi to vga adaptor on another computer. I plugged it straight into the vga socket on this computer and it works fine.
If that is no help, you may need a new monitor
